Answer:
By reducing the focal length
Explanation:
The power of a lens is inversely proportional to its focal length.
Mathematically, this relation can be written as
[tex]P = \frac{1}{f}[/tex]
Where, "P" represents power and "f" represents focal length. As per this relationship, the power will increase with the decrease of focal length.
Power is basically the measurement of refractive power of a lens. The refractive strength of a lens increases with the decrease in focal length.
